Connecting parallel diy 48v LFP batteries to eg 6k

[D. Abineri]

I am planning to connect two diy LFP 48v batteries to my eg4 6kXP inverter and each battery will have a jkbms (JK-PB1A16S10P).

Should I be connecting the bms comm ports? What connection do I use, what is the benefit of connecting them?

Thanks.

The benefits of connecting the bms to system is that the system will have data of battery state.
If no other battery state data is available to the system, the system will be unaware of for example SOC.
As I have no experience of your inverter, I can give no guidance of connection.

Thanks for your response. I am asking if the bms comm ports should be connected to each other and what the benefits of this connection would be.

Here are my connections. The CAN port goes to my EG4 18Kpv. There is a cable that connects the two 485B ports together. This allows the inverter to display the SOC based on the combination of both batteries. Also note the switch address positions.

Think you have answered your own question with"This allows the inverter to display the SOC based on the combination of both batteries".
Does this also allow the battery to monitored by the system and be discharged & charged according to given settings, if it does I'd say it is a worthwhile thing.

My comment was for the OP. I did not ask any question. But yes, it is worthwhile.
